Passive House certified

For projects targeting very low heat loss and high indoor comfort, Bildau & Bussmann NZ supplies high-performance timber and timber-aluminium window systems including Linea Passiva. The manufacturer describes Linea Passiva as providing outstanding thermal insulation, air and water tightness and high resistance to wind loads, making it particularly suited to passive-house requirements.

Linea Passiva is a Passive House Institute (PHI) certified window system. Its construction adds an insulating layer between the timber frame and exterior aluminium shell and can be combined with high-performance insulated glazing. Final whole-window performance depends on window size, timber, glazing and configuration, so project-specific values should be confirmed during specification.
